place sugar, corn syrup, cream of tartar and water in a heavy bottomed pot. stir to combine, and wash down sides with a pastry brush dipped in a bit of water. place on very low heat and stir until the sugar has melted and the liquid begins looks clear. cease stirring and insert candy thermometer. allow to boil, untouched until the syrup reaches 290F. don't loose patience, keep the fire on very low. at 290F, begin to watch very carefully. i like to allow the temp to come all the way to 310F, but if you are making a light colored pop, you may want to stop at 300F, as the sugar begins to develop a color around 295F. when you reach your desired temperature, add the food color and flavoring, and swirl to incorporate. keep the pot on the fire and allow it to come back up to temperature (300F or 310F respectively).

carefully pour into your molds, or onto a greased sheet of foil. add sticks and then allow to cool at room temperature.
